Interfaces

In addition to the typical TcCOM interfaces, the TcPowerMeasureEL34x3 modules offer two specific interfaces for supplementary modules.

ITcPowerMeasure

Using the ITcPowerMeasure interface, downstream modules can reference the measure process data directly and in a structured manner without the need for additional mapping (see Measurement data).

ITcPowerInputDPM

The interface ITcPowerInputDPM enables the use of Distributed Power Measurement (DPM) by providing the measured voltages for downstream modules without the need for additional mapping.

Modules such as TcPowerMeasureEL3444 and TcPowerMeasureEL3446 can access the DPM process data via this interface and transmit it to the associated EtherCAT Terminals. These terminals only record currents and receive the required voltage information via the DPM data to determine power and other measured variables.
